Usual the antenna design for TX and RX at the same side, and the space between RX1 & RX2 is λ/2 at the same horizontal level which shown as below.
It can get the object position by (x, y,) in 2D.
Because of some reason, our design of antenna is as below picture, TX and RX at the opposite side and RX1 & RX2 not at the same horizontal level.
Will it get the same object position (x, y) in 2D?
Many thanks.
